Scam #1 Details
1) The first scam begins with the fraudster making a telephone call claiming to be from MasterCard® or Visa® and wanting to verify unusual purchases on an account.
2) Since there were really no purchases made, the cardholder will state the transactions are not valid and is then told by the scam artist that a credit will be issued to his or her account.
3) The caller will then say he or she needs to confirm that the cardholder has possession of the card, so he or she will ask for the three-digit code on the signature panel of the card. For Visa cards, this code is the Card Verification Value 2 (CVV2), and for MasterCard it is the Card Validation Code 2 (CVC2).
4) If the cardholder provides that code, the caller will indicate the code verifies the card is in the cardholder's possession and hangs up. The fraudster now has that three-digit code in conjunction with the card number and expiration date they already know. The person can now begin making fraudulent Internet or telephone purchases.
5) Typically, if you receive a call claiming to be from MasterCard, the next day you may receive one claiming to be from Visa or visa versa.
Scam #2 Details
1) A fraudster posing as a representative from MasterCard or Visa asks cardholders for account information to confirm a prize they have supposedly won.
2) The caller may already have some information about the cardholder, such as name, card number, and card expiration date.
3) The caller asks questions to get the three-digit code for Visa (CVV2) or MasterCard (CVC2). Once he or she has this information, the scam artist can shop online or by telephone.
Scam Information
These requests sound legitimate. In both scams, the fraudsters go as far as providing employee identification numbers and fake names. They sometimes give the cardholders a reference or control number and advise them to call the toll-free telephone number on their card if they have questions.
Neither Visa nor MasterCard make calls directly to cardholders and would never call to ask for any proprietary information, including the CVV2 or CVC2 codes. Do not respond or disclose any personal information, account details, or card information to anyone who initiates contact with you by telephone.
